SPECIFICATION forming part of Letters Patent No. 555,870, dated March 3, 1896. Application iiled June 22,1895. Serial Noi 553,772. (No model.)

.To @ZZ whom, t may concern,.-

Beit known that I, GEORGE XVM. MANUEL, residing in the city of New Orleans, in Orleans parish, and State of Louisiana, have invented a new and Improved Furnace- Gleaner, of which the following is a specification.

My invention relates more particularly to a grate-cleaning device for furnaces, and it primarily has forits object to provide a gratecleaning means of a simple and economical construction which will serve to effectively clean the furnace-grate, and which can be easily manipulated from the outside of the furnace without requiring the f urnace-doors to be opened.

My invention also has for its object to provide a grateecleaning mechanism which will serve to raise the clinkers and prevent same from forming into large portions.

Vith other objects in view my invention consists in the peculiar combination an d novel arrangement of parts, such as will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my improved grate-cleaning devices, the same be ing shown set to their inoperative position. Fig. 2 is a similar view showing the same set to their elevated or operative position. Fig. 3 is alongitudinal section of a portion of a furnace,showin g my improved grate-cleaning devices as applied for use, the same being shown set to an inoperative position in dotted lines; and Fig. 4 is a partial horizontal section of the furnace, and showing the gratecleaning devices in plan view.

My improved grate-cleaning device is in the nature of a series of roller or disk members which are adapted to be projected up between the grate bars and reciprocated longitudinally between such bars by means of a suitable handle projected beyond the front of the furnace, such disks being mounted upon suitable guideways which, by means of a handlever mechanism operated from the outside of the furnace, can be quickly adj usted to elevate the said roller-disks to bring their upper portions between the grate-bars, or lowered to hold such disks below the grate and out of the iire or intenseheat surface of the grate.

lVhile I prefer to employ the detail arrangement of the mechanism shown in the accompanying drawings for raising or lowering the cleaner-disks, yet I do not confine myself to such details, as these may be varied without departing from the scope or broad ideas of my invention. 1

Referring now to the accompanying drai ings, A indicates the front wall of the furnace, B the bridge-wall, and C the gratebars, all of which may be of an y ordinary construction.

D D indicate a pairof horizontal guide or track ways, which are disposed at a Vsuitable distance below the grate, in the ash-pit preferably, by projecting one end, d,V into the bridge-wall and securing the other end, d', to the furnacewfront A, as shown. Upon these guides D is held to travel, reciprocally, a carriage EX, consisting of grooved rollers c e, joined by a transverse shaft or bar e' e and a pair of rearwardly and upwardly extending arms E E, which have their lower ends e2 e2 pivotally connected to the shaft or bar e', as most clearly shown in Fig. l. of the drawings.

The upper ends of the arms E E are pivotally joined to the inner ends of a pair of rods F F, the front ends of which are in turn hinged or pivoted to the front wall of the furnace, preferably to a separate casting G, bolted to such furnace-front, as most clearly shown in Fig. et.

II indicates a transverse shaft provided with grooved rollers h 7L, which rest on and are adapted to be reciprocated back and forth on the rods F, in the manner presently described. Upon this shaft is mounted a series (eight, more or less) of disks J held to turn with or independently of the shaft ll, and to such shaft centrally thereof is secured a leverrod K, which extends forward through a slotway t in the front wall of the furnace, the front end terminating in a handle It'.

L indicates a lever-rod secured centrally to the rod e, projected forward through the furnace-front and provided with a handle l, as shown.

The several disks J are held spaced apart on the shaft l-I by cuff-members I or other suitable means.

By referring more particularly to Fig. 3 of the drawings it will be seen that by pushing IOO the lever L inward the carriage EX will be forced rearward and the arms E E thereof to a vertical position, connectionof such arms with the rods F F being of such a nature that when they assume their vertical position they lift the rods F F to a horizontal position and raise the axle Il and the disks to such a point that the upper ends of the said disks are projected between the grate-bars, it being manifest that when in this position by manipulating the lever K such disks can be reciprocated between the grate-bars, they traveling with the guide-rods F, it being also obvious that to throw the said disks J J out of operative position it is only necessary to pull the lever L outward to the position shown in Fig. l.

From the foregoing description, taken in connection with the drawings, it is thought the advantages of my improvement will be readily appreciated by those skilled in the art to which it appertains. It will be seen that the grate-cleaning operation can be quickly effected without opening the furnacedoors.

Being capable of operation from the outside of the furnace the grate can be frequently cleaned to thereby keep all ashes out of the furnace, and thereby give a more perfect and even draft through the grate-bars and reduce the danger of the said bars warping` or burst-ing out to a minimum.

My improved grate-cleaning devices will be found especially useful when burning line or other slack coal which bakes or runs together, as the same will serve to break up such slack-coal thoroughly without opening the furnace-doors, which would allow the entrance of cold air just where it ought not to go. The same is the case in raising clinkers or cleaning furnace by the ordinary methods, which usually has to be done every six hours with a great loss of time.

Thus it will be seen that by my improvement the grate can be cleaned as often as desired during the day without letting cold air under the grate, thereby not only preventing a loss of time but a large per cent. of coal, as well as lengthening the life of thegrate-bars.

My improvement is also a great labor-saver, as it makes furnace-firing much easier, and the same can be used on any straight-bar grate.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An improved grate-cleaner, comprising a series of disks adapted to travel between the grate-bars, a lever-rod for moving said disks back and forth, and a track for guiding the movement of said disks substantially as shown and described.

2. An improved grate-cleaner comprising` a series of disks mounted upon a shaft and adapt-ed to travel between the grate-bars, a lever-rod for moving said disks and a track upon which the disk-shaft moves, said track being vertically adjustable substantially as shown and described.

3. An improved grate-cleaner comprising a vertically-swin gin g trackway,operated from the outside of the furnace, and a series of disks held to reciprocate on the trackway adapted when such trackway is raised to project between the grates, and having a handle or lever member projected through the front wall of the furnace substantially as shown and for the purpose described.

4. An improved furnace-grate cleaner comprising trackways held under the grate, capable of being adjusted to a horizontal or inclined position, and having lever mechanism for adjusting it projected beyond the front wall of the furnace, and a rake consisting of a transverse shaft held to reciprocate on the said trackways and supported thereon, said shaft having a series of disks adapted to project up between the grate-bars and a lever secured to the rake-shaft, at one end and having its front end project through the front wall of the furnace all arranged substantially as shown.

5. An improved grate-cleaner comprising a pair of fixed horizontal guides held under the grate a carriage held to travel thereon having a pair of rearwardly and upwardly extending pivoted arms,a pair of upper guides hinged at their front ends to the furnacefront and pivotally joined at their rear ends to the upper end of the carriage-arms, a transverse shaft having roller-bearings supported and held to reciprocate on the upper guides, a series of disks carried bythe shaft, andthe lever-rods K and L secured respectively to the shaft and the carriage all arranged substantially as shown and for the purposes described.
